[Solved] Nvidia GTX 1050 is not working on Gentoo Linux

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

If clinfo lists something as root, but not as the fahclient user, it's likely a permissions issue still. Does your system have a "render" group?


After a system update, now running clinfo as fahclient user won't have a segfault any more. now the result is:

But the error persists.

I removed eselect-opencl, as it's obsolete, and doesn't solve the problem.

Is there some way to force FAH to use the Nvidia platform while the Mesa platform is still present?

I know you need Mesa for Crossover, but perhaps you could temporarily disable it and see if GPU folding works when you do that? That would at least isolate the error.

Ohh, thanks! That solved the problem.

Gentoo is a compile focused distro, so can you recompile MESA without the options "--enable-opencl" and "--enable-opencl-icd"? I doubt any programs you use would require Mesa OpenCL when you have another OpenCL implementation. That might let you keep using applications which use MESA for graphics.

Devs: Is there a plan for FAHClient to work in the presence of multiple OpenCL platforms, and pick the best one?

Thanks!

crossover wants me to compile mesa with opencl enabled, but I disabled it anyway.

The NVidia GPU works with the NVidia OpenCL package (and apparently not with the Mesa OpenCL). FAHClient has been having troubles when two versions of OpenCL are installed. That problem is being debugged by dis-allowing more than one version. It's not clear how this issue will ultimately be resolved.
If you're an experienced Linux Guru, you can probably figure out what changes to your path or to hard-links might be needed but I can't guarantee any of those tools will work. During the debugging process, things might change, too.

Removing Mesa OpenCL works, too.
